Abstract

A method is described of protection against fire with coating and paint compositions for houses, polymer constructions, industrial installations, transport vehicles in which polymeric products produced by processing polystyrene and copolymers to macroplegmatic structure are introduced with introduction of ionic grouping at high density thus acquiring the potential to absorb water up to 400 times weight endomolecularly very strongly. They can be used in paint and general coating compositions as first surface coating or to be in paint water emulsions as main coating. Inorganic materials such as lime, gypsum, silicones, etc., can also be added. The products in the coating compositions when burned of decomposed in fire edges release much water and quench the fires immediately offering complete protection against fire.

Description

FIRE RESISTANT COMPOSITIONS

The invention described relates to an innovation introducing an original fire resistant coating composition.

Fires constitute a critical problem of life and of security for man today resulting to insecurity of life in houses, in community events and in the environment and a public opinion is formed that all those should be offered with fire protection, with fire resistant constructions.

The houses being constructed with inorganic materials and with cement, stones and bricks are not flammable. However, the additions, the artistic wood articles, the electrical cables, the telephone connections and all the surfaces being coloured with organic dyes are introducing into houses elements of construction which burn resulting to insecurity and to discomfort. The rest which make property outside the houses, transport, halls, places for civil actions, etc. all contain mostly flammable material and frequent polymer construction creating conditions that lead to fire and are burned vigorously and fast .

The scientific conception to face those life problems is for introducing fire safe regulations in the construction of houses and in the transport of goods having for scope the protection against fire, which has resulted to an international scientific mobilisation to provide such solutions . We have dealt with that problem and have worked out to create solutions providing protection against fire in the creation of fire resistant surface coatings. We have invented surface coating composition introducing in houses and in life goods protecting from fire with fire resistant coating.

The innovative compositions we have developed and tested are coatings formulated so that the first coating surface contains products which have absorbed water so that the coating composition acquires fire resistant properties. Those added products are polymetric multiprocessed products becoming macroplegmatic of high stability permitting the introduction in them of ionic groupings at high density after which they acquire properties to absorb much water endomolecularly up to 400 times by weight keeping that water very strongly (we need to apply high pressure to take it out) .

The polymeric products which are multiprosessed to become macroplegmatic of c 30.00O to 50.000 which can absorb much water endomolecularly are derived from polystyrene and copolymers recycled or new, that is, are derived from market highly available and used polymers which show surface coating affinity to all organic coating compositions .

These products that advance fire resistant action can form a lower own surface in the coating where adherence and coat covering is offered. Or they can be added to the main coating composition specially to coloured coatings which are applied in water emulsions. And then added in those formulations are inorganic materials which do not burn such as lime, gypsum, silicones etc. in pulverised form so than they make a main uniform surface with complete fire protection.

It is obvious that the solution advanced for fire protection apart of originality and high profitability also can be employed in a good number of coating compositions, which can coat all that need to be fire protected, in house protection, in machinery protection, in transport vehicles protection, in inflammable operations and installations. The protection offered by those products is high since by being burned or decomposed they are releasing much water up to 400 weight times on the fire edges resulting to spontaneous fire quenching offering thus complete protection against fire.

EXAMPLES

The ability of those coated compositions which contain fire resistant products were demonstrated in a number of cases .

a. Electrical cables which were coated with a composition containing 5% of these products showed high fire resistant action. b. Wood constructions which were coated with emulsion paints containing the products in proportion higher than 3% did not burn. c . Polymer sites in a car which were coated with a coating composition containing 6% of these products did not show ability to burn. d. Industrial installations processing petroleum products being coated with a paint containing those products in quantity more that 5% did not burn. e. Coating with water emulsion paints in houses and the equipment in houses which contain those products at quantity more than 3% did not burn.

With those application results we feel that the high potential in fire resistant action of those products described is shown.

Claims

1. Method introducing fire resistant action with coating compositions for cables, house articles, polymeric constructions, industrial installations and industrial procedures producing flammable and explosive products , by introducing in those coating compositions products that contain endomolecularly water up to 400 times their weight which is kept strongly (needing to apply pressure to take it out ) .

2. Method according to claim 1 by which in the coating and paint composition are introduced processed polymeric products of polystyrene and copolymers which absorb water up to 400 times their weight and keep it endomolecularly and powerfully and these products when are burned or decomposed in the fire edges release the much water contained resulting to spontaneous quenching of fires.

3. Method according to claims 1 and 2 by which the fire resistant products constitute a first coating surface and over it is added the paint and the main coating or are mixed with emulsion paints or are mixed with non burning inorganics such as lime, gypsum, silicones etc. in pulverised form.

4. Method according to claims 1 and 2 by which with the addition of fire protection products to the paints applied in wood constructions to the paints used in houses, to coating for cables, to industrial constructions and equipment, to transport vehicles, complete protection from fires is achieved.

5. A method according to claims 1 to 4 by which with the introduction, to the coating or paints compositions in houses, in wood constructions, in polymeric constructions, in industrial installations producing flammable or explosive products etc., processed polymers from polystyrene and copolymers to macroplegmatic structure which absorb intermolecularly very strongly water up to 400 time weights which being added to coating or painting compositions in quantities 3-10 % w/w introduces complete protection against fire because when those products are exposed to the fire edges are burned or decomposed and release much water so that the fires are spontaneously quenched.
